Run Ruby scripts

Name

In this field, specify the name of the current run/debug configuration.

Ruby script

Specify the fully qualified path to a Ruby script to be executed, or click, and select the desired Ruby script in the dialog that opens.

Script arguments

Specify command-line arguments that will be passed after the script's filename. These arguments will be available to your Ruby program in the global ARGV array. For example:

• Pass the following values as Script arguments: "Jet" "Brains".

• Run the following Ruby script:

  puts "Hello, #{ARGV.join}! I'm Ruby!"

  A program will return Hello, JetBrains! I'm Ruby!.

Working directory

Specify the working directory used by the running task. For example, this option is in effect when the running script loads other scripts by relative paths.

Environment variables

Specify the list of environment variables as the name-value pairs, separated with semi-colons. Alternatively, click to create variables and specify their values in the Environment Variables dialog.

Ruby arguments

Specify the command-line arguments to be passed to the Ruby interpreter.

Note that when JRuby is used as the project interpreter, the list of Ruby arguments can include Nailgun argument --ng.

When such a run/debug configuration is launched, RubyMine analyzes the running processes, and does one of the following, depending on the presence of the running Nailgun server:

• If there is no running Nailgun server, or if there is a Nailgun server on a non-default port, or with a different gemset, then RubyMine suggests to specify the desired port number.

• If a Nailgun server runs on the default port with the required gemset, RubyMine does nothing.

• If a Nailgun server runs on a different port with the required gemset, then RubyMine suggests to specify the desired port number.

• If a Nailgun server runs on the default port with a different gemset, then RubyMine deletes the --ng argument.

Classpath property is added to Nailgun settings.

Ruby SDK

Specify the desired Ruby interpreter. You can choose the project default Ruby SDK, or select a different one from the list of configured Ruby SDKs.

Execute in the context of Rails

This option is available for scripts in Rails applications. You can enable it to run scratch or project Ruby scripts in the Rails context.
